Advantages of dual channel β online monitoring system

The ZWIN-YCB06-D dual-channel continuous particle monitoring system adopts the principle of β-ray method monitoring, uses low-energy C14 as the source of β-rays, and calculates the change based on the amount of β-rays passing through the clean filter paper and the filter paper with collected particulate matter. Collect the mass of the particulate matter on the filter paper, and then obtain the concentration of particulate matter in the air. The inspection standard of the equipment is based on the national standard, which has the characteristics of preventing dust and splashing water.

At present, most β-ray method atmospheric particulate matter monitors on the market are single-channel monitoring instruments, and only one parameter can be measured. On the basis of the original single-channel β-ray particle online monitor, our company has designed and developed a dual-channel particulate online monitoring instrument. The integration of online monitoring and management of dust pollution on construction sites has improved the efficiency and ability of scientific management. It is more authoritative to grasp the true status of the dust pollution at construction sites and the effects of dust control measures. The product can be widely used in dust monitoring of urban functional areas, dust monitoring of industrial enterprise boundaries, dust monitoring of construction site boundaries, dust monitoring of social life, etc., with high precision characteristics.

The dual-channel β-ray method of dust on-line monitoring products has the following advantages:

Using the national standard method of β-ray detection principle, the value is more accurate; compared with other similar single-channel products in the current market, the monitoring cost is greatly increased, and related departments and enterprises can simultaneously carry out the concentration of particles with different particle sizes in a more economical form. Measurement; users can install any two particle size particle sampling heads on the same device according to actual needs, which can simultaneously measure the particle size concentration of two particle sizes (PM2.5/PM10/TSP, choose two out of three), Easy to use, high cost performance; Freely set interval and flow rate; RS485+GPRS multiple output transmission methods, can be connected to computer, modem, printer or data collection system for data retrieval; Through network & station mutual access can achieve all-weather Remote unmanned operation, uninterrupted data; simple and fast on-site calibration (using a universal FRM calibration membrane); accurate and stable data, reliable and simple mechanical structure and airflow system, mature system platform technology; hourly filtration to reduce volatility The influence of compounds; the host can measure air temperature, air humidity, light, atmospheric pressure, wind speed, wind direction and other meteorological elements at the same time; through advanced heaters, accurately control the relative humidity of the sample; while monitoring, it can automatically part of the sample Seal and keep the bottom for inspection; Built-in air conditioner to ensure the internal temperature of the product, the value is more stable.
